To prevent unnecessary malfunctions during CNC system operation in CNC 4-axis turning, CNC machine operators should carefully read the relevant operating instructions before operating the machine. They should fully understand the functions of the CNC system and be familiar with the functions and precautions of each key, button, and switch on the CNC system and machine operator panel.
To ensure proper operation of the CNC system, during initial commissioning or after relocation, perform the following system inspections:
1. Verify Power Supply Specifications
- Confirm that the AC power supply specifications meet the requirements of the CNC machine, focusing on rated voltage, frequency stability, and supply capacity.
- Ensure that the supply voltage fluctuation is within the machine’s allowable range (typically ±10%), and that grounding of the power input is reliable.
2. Check Cable Connections and Components
- Carefully check that all cables connecting the CNC machine to external devices are correctly and securely connected according to the instructions in the provided connection manual.
- Connecting a 4-axis CNC system involves linking the CNC controller with its corresponding feed drive units and spindle drive units. This mainly includes connecting external power and signal cables.
Before power-on, carefully inspect:
- CNC control unit
- MDI/CRT or display panel
- Position display module
- Input device (such as paper tape reader or USB interface, depending on model)
- Power supply module
- All printed circuit boards
- Servo drive units
Additional requirements:
- Address or replace any damaged or faulty components promptly.
- Ensure connectors and printed circuit boards are securely seated and fully locked.
- Confirm that all plugs, terminals, and fastening screws are tightened.
3. Verify Hardware Settings
- Ensure that the hardware settings on the printed circuit boards inside the CNC equipment comply with the manufacturer’s specifications.
- This includes the correct configuration of jumpers, DIP switches, and adjustable potentiometers.
- Confirm that these settings match the machine parameters and options installed.
4. Inspect Protective Grounding
- Carefully inspect the CNC 4-axis machine’s protective grounding system.
- CNC machines must have a reliable grounding connection to:
- Ensure operator and equipment safety.
- Reduce or eliminate electrical noise and interference.
- The protective ground must be securely connected between the servo drive units, servo transformer, control cabinet, and the workshop ground system.
Only after completing the above checks and confirming that all items are correct should the CNC 4-axis turning machine be powered on for operation.
